TRANSCRIPT
Isco Non-Contact LaserFlow™ Velocity SensorThe LaserFlow™ remotely measures flow in open channels with non-contact Laser Doppler Velocity technology and non-contact Ultrasonic Level tech-nology. The sensor uses advanced technology to measure velocity with a laser beam at single or mul-tiple points below the surface of the wastewater stream. (Patent Pending)
The LaserFlow is ideal for a broad range of wastewater monitoring applications. It is compatible with both the Teledyne Isco Signature Flow Meter and the Teledyne Isco 2160 LaserFlow Module, depending on the type of installation.
During submerged conditions, flow measurement continues without interruption with optional Doppler Ultrasonic Area Velocity technology.
With its specially designed mounting bracket in place, the LaserFlow can be deployed and removed from above ground, eliminating unsafe and time-consuming confined space entry. A variety of communication options enable programming and data retrieval from a remote location. Information about data quality can be recorded and transmitted alongside the flow data.
Applications Permanent and portable flow measurement for
CSO, SSO, I&I, SSEs, CMOM, and other sewer monitoring programs.
Shallow flow measurement in large and small pipes.
Wastewater treatment plant influent, process, and effluent flow measurement.
Industrial process and discharge flow measure-ment
Stormwater conveyance and outfall(sunshade required)
Irrigation canals and channels(sunshade required)
Standard Features Non-contact velocity and level measurement Single or Multiple Point measurement below the
liquid surface Robust, submersible enclosure with IP68 ingress
protection No deadband from measurement point in non-
contact level and velocity measurements. No need for manual velocity profiling Bidirectional velocity measurement

Below Surface
Single- or Multipoint MeasurementDepending on your application needs, the LaserFlow™ device can be programmed to take velocity measurements at single or multiple points below the water’s surface, producing an accurate mean velocity reading.
System VersatilityFrom industrial applications to manhole installations, the LaserFlow’s versatile configuration options give you the flexibility to measure flow in most open channel applications. The sensor is compatible with both the Isco Signature™ Flow Meter for permanent discharge compliance monitoring, and the Model 2160 LaserFlow Module for everything from portable surveys to permanent installations.Both flow meters have a variety of communication options for remote data access and programming, eliminating the need for frequent site visits.

Optional SubmergedFunctionalityDuring submerged conditions, flow measurement continues without interruption with the optional TIENet™ 350 Area Velocity sensor, which combines Doppler Ultrasonic velocity measurement with Differential Pressure level measurement.
Optional RedundantMeasurementFor redundant flow measurement at critical monitoring sites, a unique flexibility is added by the optional TIENet 350 AV sensor when mounted at the bottom of the pipe.The 350 provides redundant velocity, level, and flow data from the same site as the LaserFlow device.
Easy and Secure Retrieval/ReplacementWithout Manhole EntryFollowing initial installation and adjustment, the sensor can be installed or removed as needed without manhole entry in most situations, using the optional retrieval arm(shown at left) to grasp the handle.The handle’s simple but effective locking mechanism (shown below) holds the sensor firmly in place, and is easy to engage and release from above ground.
